Revert 132887 - Update lzma_sdk to 9.20

Copied only C code required to open 7z archive files and
uncompress LZMA compression.
Updated chrome/installer/util/lzma_util.cc to follow API
changes.

BUG=None

-    7+:   64 MB   1    64
- 
-  The default value for "level" is 5.
-
-  algo = 0 means fast method
-  algo = 1 means normal method
-
-dictSize - The dictionary size in bytes. The maximum value is
-        128 MB = (1 << 27) bytes for 32-bit version
-          1 GB = (1 << 30) bytes for 64-bit version
-     The default value is 16 MB = (1 << 24) bytes.
-     It's recommended to use the dictionary that is larger than 4 KB and
-     that can be calculated as (1 << N) or (3 << N) sizes.
-
-lc - The number of literal context bits (high bits of previous literal).
-     It can be in the range from 0 to 8. The default value is 3.
-     Sometimes lc=4 gives the gain for big files.
-
-lp - The number of literal pos bits (low bits of current position for literals).
-     It can be in the range from 0 to 4. The default value is 0.
-     The lp switch is intended for periodical data when the period is equal to 2^lp.
-     For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
-     better to set lc=0, if you change lp switch.
-
-pb - The number of pos bits (low bits of current position).
-     It can be in the range from 0 to 4. The default value is 2.
-     The pb switch is intended for periodical data when the period is equal 2^pb.
-
-fb - Word size (the number of fast bytes).
-     It can be in the range from 5 to 273. The default value is 32.
-     Usually, a big number gives a little bit better compression ratio and
-     slower compression process.
-
-numThreads - The number of thereads. 1 or 2. The default value is 2.
-     Fast mode (algo = 0) can use only 1 thread.
-
-Out:
-  destLen  - processed output size
-Returns:
-  SZ_OK               - OK
-  SZ_ERROR_MEM        - Memory allocation error
-  SZ_ERROR_PARAM      - Incorrect paramater
-  SZ_ERROR_OUTPUT_EOF - output buffer overflow
-  SZ_ERROR_THREAD     - errors in multithreading functions (only for Mt version)
